PASCO2V01BUMA1

PASCO2V01BUMA1 is a XENSIV™ PAS CO2 gas detection sensor. It has leveraged its knowledge of sensor and MEMS technologies to develop a disruptive gas sensor for CO2 sensing. It is a real CO2 sensor in an exceptionally small form factor based on the photoacoustic spectroscopy (PAS) principle. It is optimized for low-frequency operation and detects the pressure change generated by CO2 molecules within the sensor cavity. CO2 concentration is then delivered in the form of a direct ppm readout due to the integrated microcontroller. It is highly accurate CO2 reading is guaranteed. Ideal high accuracy, compact size, and SMD capability make the XENSIVTM PAS CO2 ideal for indoor air quality monitoring solutions in the market with numerous potential applications, VAC (Heating, Ventilation, Air Conditioning), home appliances, smart home IoT devices, agriculture/ greenhouses, in-cabin air quality monitoring unit.
